Ultrasound echo-intensity predicts severe pancreatic affection in cystic fibrosis patients.

ABSTRACT:

Background

Pancreatic destruction affects the majority of patients with cystic fibrosis. We aimed to relate ultrasound findings to exocrine pancreatic function and cystic fibrosis genotype.

Methods

Patients with cystic fibrosis and a matched group of healthy controls were included. We performed transabdominal ultrasound, and recorded echo intensities of the pancreas and parenchymal characteristics according to endoscopic ultrasound based Rosemont criteria.

Results

We included 39 patients and 29 healthy controls. The cystic fibrosis patients were grouped according to exocrine pancreatic function; Cystic fibrosis, insufficient (n = 20) and sufficient (n = 19). Echo intensity measures and visual score demonstrated hyper-echogenicity in the pancreas insufficient group compared to the pancreas sufficient groups (p<0.001). Ductal and parenchymal changes were not prevalent in any of the groups.

Conclusion

The hyper-echoic pancreas was the most frequent ultrasonographic finding in exocrine pancreas insufficient cystic fibrosis patients. Pancreatic echo levels correlated to pancreatic phenotype.

Project description:Liver disease is the third leading cause of death in patients with cystic fibrosis (CF), but features of patients with CF, severe liver disease, and portal hypertension have not been characterized fully.We performed a retrospective analysis of data from 561 patients with CF (63% male, 99% with pancreatic insufficiency), liver disease (hepatic parenchymal abnormalities consistent with cirrhosis, confirmed by imaging), and portal hypertension (esophageal varices, portosystemic collaterals, or splenomegaly), with no alternate causes of liver disease. All patients were enrolled in the Genetic Modifier Study of Severe CF Liver Disease at 76 international centers, from January 1999 through July 2013.Male patients were diagnosed with liver disease at a younger age than female patients (10 vs 11 y; P = .01). Splenomegaly was observed in 99% of patients and varices in 71%. Levels of liver enzymes were near normal in most patients. Thrombocytopenia affected 70% of patients and was more severe in patients with varices (88 × 10(9)/L vs 145 × 10(9)/L; P < .0001). Ninety-one patients received liver transplants (16%), at a median age of 13.9 years. Compared with patients who did not receive liver transplants, patients who received liver transplants had lower platelet counts (78 × 10(9)/L vs 113 × 10(9)/L; P < .0001), higher international normalized ratios (P < .0001), and lower levels of albumin (P = .0002). The aminotransferase to platelet ratio index (APRi) and fibrosis index based on 4 factor (FIB-4) values were higher than the diagnostic thresholds for CF liver disease in 96% and in 90% of patients, respectively. Patients who received liver transplants or who had varices had higher APRi and FIB-4 values than patients who did not.In patients with CF, severe liver disease develops early in childhood (approximately 10 years of age), and is more common in boys than in girls. Patients with varices and those who receive liver transplants have more abnormal platelet counts and APRi and FIB-4 scores.
